ANDRZEJ LAPKA, OF SIMPSON, PENNSYLVANIA.

Application filed. February 9, 1920.

To all whom it may concern:

Be it known that I, ANDRZEJ LAPKA, citizen of Poland, and resident of Simpson, in the county of Laclrawanna and State of Pennsylvania, have invented certain new and useful improvements in Churns, of which the following is a specification.

This invention relates to improvements in churns, and has for principzl object the provision of a water-driven churn which will thoroughly and completely stir the con tents of the churn, and which is at the same time a labor saving and inexpensive device.

The above and other objects will become apparent in the below, in which characters of reference will refer to-lilrenamed parts in the accompanying drawings.

Referring briefly to the drawings, Figure 1 is aside elevational view of my device showing the manner of its attachment to a water supply.

Fig. 2 is a front view of the same, partly in elevation and partly in section.

Referring now in detail to the drawings, the numeral 1 represents a faucet and 2 a hose connected thereto and leading to a water motor 4': through an inlet 3. Said water motor comprises the usual bladed or vaned wheel 6 which is rotated by the water entering through the inlet 3, and a shaft having a beveled gear '7 is turned by said whee. A frame 15 is mounted to a support such as, in the illustration, the wall of a house, and vertical shafts 9 and 1e are supported therein, and a horizontal shaft 16 is supported in an upper extension 16 of said frame. As shown, bevel gears 8 and 10 are mounted on the shaft 9, 11 and 12 on the shaft 16, and 13 on the shaft 1%. These gears are made to form train, together with the shafts mentioned, and requiring no further description from the clarity of the drawing, by means of which the water wheel causes rotation of the shaft 14. An other vertical shaft 19 is coupled to the shaft 14 by a coupling 18, and the lastnamed shaft enters into a funnel-shaped chamber 20, the lower end thereof resting in a cupped boss 22 as a bearing.

ber 20 is hollow, and serves to hold the butter or other material about to be stirred into a cream. That portion of the shaft 19 contained within the chamber 20 is provided with horizontally extending wings or blades 2-5, whose function is to give rapid rotation to the mass in-the chamber in a horizontal direction. In order to produce a thorough and complete mixing of said mass, 1 have provided additional mixing means as follows: Horizontal rigid shafts are secured. to the inner wall of said chamber, indicated by 2%, 25, 26, and 27. The shaft 2% has vertical blades 35 pivotally mounted thereon, and the mounting is such that a portion of the outer edge of each blade 35 will, in turn, stand in the path of the upper blade 23, so that the blades 35 will be turned by the blade 23. Similarly the upper blades 28 will be turned by the upper blade 23, and the middle blades 28 by the middle blade 23. The operation of the blades and 30 is, from the above, and by reference to Fig. 2, apparent without further description. Thus it is seen that the blades 35 turn in a direc tion opposite to that in which the upper blades 28 turn, and so with the remaining vertical blades, each turns in a direction 0pposite to that of its immediate neighbor. Thereby, together with the stirring motion of the horizontal blades 23, a thorough mi):- ing of the material in the chamber 20 is assured.

I claim:

A churn comprising a chamber having a vertical shaft pivotally mounted therein, means for turning said shaft, spaced apart horizontal blades rigid to said shaft, supported in the wall of said chamber, vertical blades pivotally mounted on said shafts, said last-named blades lying in the paths of said first-r amed blades so that some of said last-named blades are rotated in one direction, and others in the opposite direction.
